Hi

I am using some ‘collection\_select’ combo boxes (w Ajax calls) , it’s  
working fine, here is my partial  
\_property.rhtml

\<%=  
@properties = Property.find\_by\_owner\_id(owner\_id)  
collection\_select(:property, :name, @properties, :id, :name,  
options = {:prompt =\> ‘â?? Select a Property â??’}  
)  
%\>

but I got a small new-ror-ies problem :  
when @properties contains only one element, I would like to avoid  
selecting the prompt and rather select this unique element…  
What should I do ?

complementary questions on Rails :  
1- where can I find a list of the available options ?  
are :prompt and :selected they only available options… could not  
find it in RoR book…  
2- why not a dedicated newsgroup to Rails … complementary of Ruby …

thanks to all

kad
